DRAFT-HIGGINS FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed January 7,1904. Serial No. 188,098.

To col], whmn it may concern:

Be it known that I, SAMSON D. Wnrenr, a citizen of the United States ofAmerica, and a resident of Cleveland, county of Cuyahoga, and State ofOhio, have invented certain new and useful Improvements in Draft-Riggingfor Railway-Oars, of which the following is a specification.

My invention relates to improvements in draft-riggings for railwaycars,which are more particularly intended for so-called in dustrial cars; andthe object of my improvement is to construct and arrange said rigging insuch manner as to assure at all times of a proper adjustment of thedrawbars with regard to the curves around which a train of cars issupposed to proceed. I attain this object in and with a draft-riggingconstructed and arranged substantially as shown in the accompanyingdrawings, in which Figure 1 represents a partial plan view of coupledcars, one being on the straightpart and the other on the curved part ofa railway track. Fig. 2 is an enlarged horizontal sectional view of asingle draw-bar and the rig. ging therefor on line co 01:. (See Fig. 3.)Fig. 3 is a transverse sectional view on line y y, (see Fig. 2,) andFig. 4 is a side elevational view of the same.

Like letters of reference denote like parts in the drawings andspecification.

The characteristic feature of my invention f consists in the novelmanner of supporting and guiding horizontally-swinging draw-bars inorder to retain said bars in proper alineniont in passing around curves,thereby avoidin undue strains upon said bars and the ten ency ofuncoupling same.

Unlike other draftriggings, which swing the draw-bars concentric withthe king-bolt center, I provide a pivotal support for said barsintermediate the end sill and the bodybolster of the car, the rear endof said bars being equipped with a spring-carrying cage which furnishesthe pivots for the bar and the position of said cage being controlledfrom and by the truck-bolster through the intervention of guide-rodshereinafter referred to.

In Fig. 1 an illustration is presented show- From this illustration itcan readily be seen how the position of the draw-bars can be affected inorder to suit the radius of any curve re gardless of the wheel-base andthe length of cars. Draft-riggings of this type are more particularlyintended for use in connection with industrial railways, (mines andother plants handling raw material,) since the track of such railwaysoftentimes has sharp curves, and the cars operated thereon are bynecessity of peculiar construction, which present propositions notexperienced in ordinary railroading.

In the illustration herewith given my invention is shown in connectionwith a so-called steel car, channeled beams being used for carframe A,the car-bolster B, the truckbolsters C O, and the intermediate sills DD. (See Figs. 2 and 3.) This invention, however, is equally as wellapplicable in connection with wooden car-frame constructions.

The drawbar E is preferably cast of malleable iron and is of the MasterCar-Builders standard type.

To the rear of the bar is secured the rod F, which carries the washers ab and spring G, all of which are contained within the cage H, which inturn is held in pivotal engagement with and within the two-part casingI. Said casing I consists of the members 0 d, of which the member 0 issecurely fastened to the intermediate sills D D, as at a, and the lowermember is bolted onto the upper member, as at d. Each of these memberscontains a circular recess 6, into which extend the pivots of the cageH, (see Figs. 2, 3, and 4,) the latter being allowed to swing freelywithin said casing. The draft and buffing strains are also borne by saidcasing and the pivots of the draw-bar cage.

In pulling it is the washer c which compresses the sprin G against thecover 9 of said cage, and in buffing the spring becomes compressedagainst the rear wall g of said cage, the bar forcing the washer binwardly against said spring. The cover g may be secured to the cage inany suitable manner, as shown. This is accomplished by grooved flanges gupon the cover, which engage plain segmental flanges g on the cage. Alsothe draw-bar extends part way into said cover, as seen in Fig. 2.Furthermore, from the cage extend in opposite directions the arms h.Said arms pass through slots '8, which are formed in and by the casingmembers 0 d, the former havin free movement within the latter. The ro sJ connect the ends of said arms with the truck-frame, as shown in Figs.2, 3 and 4.. The connection of the rods upon the truclcframe, as well ason the arms, is such as to accommodate free adjustment of said rods whenand while the truck is changing its position in relation to thecar-body. Also the springs y' j are applied to maintain said rods inpropertension and to avoid j erking strains upon said rods and arms.Simply by establishing a certain prefixed distance between king-boltcenter and draw-bar pivots and the king-bolt center and points ofconnection (swivel-bearings Z) for the guiderods upon the truck-bolsterthe draw-bars may be adjusted out of alinement of the carframe in theangle as the curves in or of the track require it to be in order tomaintain the draw-bars in proper engagement under exclusion of unduestrains between and upon. said bars.

As shown, the plates K, which carry the swivel-bearings Z for the rods,can be adjusted outwardly by means of the set-screws m to compensate forwear of the connections, wheel-flanges, rails, &c.

With little attention a draft-rigging of the type' as above describedcan be maintained in proper working condition. Only few parts arerequired for this rigging, 'allof which are applied to functionate in amost rational manner and furnish cooperatively a sim le, efficient, anddurable device.

hat I claim, and desire to secure by Letters Patent, is

1. In a draft-rigging for railway-oars the combination with. the drawbar and truckbolster of a spring-cushioned cage being pivotally suported intermediate said bolster and end si of such cars, and having armsextending approximately horizontally therefrom and diverging rodsconnecting said arms with said bolster in the-manner as and for thepurpose set forth.

2; In a draft-rigging forrailway-cars the combination with the draw-barand a springcushion'ed pivoted cage supported between the king-bolt andend sill of such cars, said cage having arms extending approximatelyhorizontally therefrom, of the truck-bolster and rods extending fromnear the ends of bolster to said arms and having loose con- ,havingconnection with prising a draw-b ar having a cage attached to its rearend, a spring placed upon said end between sliding washers and allcontained within said cage, vertical pivots and horizon tal armsprojecting from said cage, a suitable support for said pivots arrangedintermediate the bolster and end sill of the car and guide-rodsconnecting said arms with the truck-bolster substantially in the manneras and for the purpose set forth.

5. In combination with a draft-rigging, a twopart casing secured to thecar-frame intermediate the bolster and end sill of said frame, the saidcasing being adapted for reception of the draw-bapspring cage andcontaining sockets for the as shown and set forth.

6. In a draft-rigging comprising the combination with the truck-bolsterand a pivoted pivots of said cage laterally-swinging draw-bar, ofguide-rods plane alinement with the tion'with said bolster as shown.

7. In a draft-rigging the combinatibh with lrly=fixedf the said cagecontaining the draw-bar of a cage and a suita casing for said cage,

the spring for said bar, having oscillating arms in vertical pivots ofsaid bar and a swiveled, laterally-adjustable connec movement withinsaid casing and lateralconnection with the truck-bolster as shown;

- and described.
